What Causes No Sound During Normal Playback of Car Navigation?
1 Answers
No sound during normal playback of car navigation is caused by a short circuit in the speaker. Below are specific reasons for common faults in car navigation systems: 1. Poor line contact: It is necessary to promptly check whether there is a loose connection in the wiring. Simply reconnect the loose part properly. 2. Aging of the power signal line: Try replacing the power signal line. 3. Prolonged screen usage: This may cause a malfunction in the power supply module. It is recommended to have it checked or replaced at a 4S shop. 4. Defective circuit design: It needs to be inspected and repaired at a repair shop or directly replaced. If under warranty, claim the warranty; if not, have it checked and repaired at a 4S shop.
